I've been looking, on and off, for the three Pullman carriages to complete my Hornby 1934 Brighton Belle. After this time, they're like hens' teeth.
But a recent visit to 'bay led me to R4512/13/14 for a mere £190. I don't know what they retailed for originally, the retail stickers were removed, but at a time when Bachmann are asking £85 for a birdcage, and the RRP* for a standard Hornby Maunsell coach is £45, ca. £60 for a Pullman with lighting doesn't seem at all bad.
OTOH, other vendors were asking £70 each, £100 each, and, in one case, £365 for the set!
And this is why people might feel that they have the preorder.
* yes, 15% retail reduction applies!
